y To ALL WHOM 1r MAY coNcERN;

Be it known that I, EDWIN CHAMBERLIN, ofthe town of Lansingburg, county of Rensselaer, State of New York, have invented a new and improved mode of securing the false bottom (to which the top of the carriage is fastened) to the seat proper; and I do hereby declare that the following is a clear, full, and enact description thereof, reference being had to the accompanying drawing forming a part of this specification', in which- Figure 1 represents carriage-seat with false bottom, secured by improvement.

Figure 2 is a vertical view of improvement.

Figure 3 is a cross-section of improvement.

Figure 4 is a cross-section with improvement inverted.

Figure 5 is a vertical view, showing double-levcr key.

The same letters refer to like parts. I

The nature ofmy invention consists in providing the seat proper with two or more hook-catches or staples,

placed at suitable points in the bottom, near the sides. These catches or staples project above the surface ofv the bottom to a. height equal to the thickness of the false or movable bottom, and the key or keys. In the falsev bottom are mede a corresponding number of holes at points directly over the catches in the seat-bottomproper, and of such size as will admit thc said catches or staples to pass readily through them. When the false bottom, with the top attached, is placed into thc seat, thc said false bottom is keyed by means ot' a corresponding number of keys attached to short hars or levers turning on a pivot at one end. It desired, the hooks or staples' may be secured to the false bottom, and made to pass through openings made in the bottom of the seat proper,

and then keyed by lever-keyson the under side.

' The advantages of this improvement are these: first, the carriage-top is as firm toits seat as if it were built to it; second, the tedious process ofscrewing and unserewing thumb-nuts or bol-ts is dispensed with.

To enable others skilled in the art to make and use my invention, I will proceed te describe it, reference being had tothe accompanying drawings, -in which- A, tig. I, represents the seat, of which B B1B, figs. 1, 3, and 4, is the bottom. Fastened in the said bottom,

at the sidesare the hook-catches a a, or staples, or their equivalents, two or more, as may be deemed suilcient.

These catches or staples a are secured by' screw-nuts n, fig. 3, or riveted or clinched. Into the false seat C, iigs. 1, 2, 3, 4, 5, are made the catch-holes O O, figs. 3 and 4, through which the catches a a pass. After the false bottom C has been properly placed in the seat A/the catches a a, projecting up through their spaces or holes o o, are keyed by the keys c k. These keys are attached to a short bar or lever, e, which turns on c. pivot at one end, as in figs. 1 and 2, or may be attached to the 'same bar e,g. 5, and swing on its centre. The hook-catches may be attached to the false bottom C, fig. 4, and pass down through the seat-bottom B and secured by the keys la c, placed and working beneath the bottom of the seat.

I do not claim.the false bottom C, as I originated it some four years or more ago, and neglected to secure it by patent, buti What I claim as my invention, vand desired to secure by Letters Patent, is-

Securing an extra bottom, C, with all the top irons attached thereto, to the seat-bottom B, by means of the double or single bars ee, furnished with the keys 7c 7c, or their equivalents, and operated either from the upper or lower side of the seat, and working into the hook-catches a a or their equivalents, which hook-catches are permanently attachedto either the extra bottom C or the bottom B, and the whole in combination, substantially as and for the purposeset forth and described.
